The AirTAC GFR400C15MJC1T AirTAC Filter Regulator NPT1/2, Manual Drain is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR400C15MJC1T is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body, on 1/2 inch NPT ports. This configuration carries the standard 40 um filter element, a manual drain you operate by hand to empty the bowl, a fitted round pressure gauge with MPa scale, and the standard regulator type with a 0.05-0.9 MPa (7-130 psi) adjustment range. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The bowl on this size is polycarbonate, and no mounting bracket is included.
This is a genuine AirTAC part from the GFR400 series. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of manual, automatic or differential-pressure drain, 40 um or 5 um filtration, gauge scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| (blank) | Pressure gauge fitted (blank). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeding filtered, pressure-regulated air to spray guns and atomising stations on a finishing line, where clean, dry air at a set pressure keeps coating application consistent.
Conditioning the air feeding carton sealers, baggers and wrapping heads on a packaging conveyor, protecting cylinders and valves from water and debris while holding set pressure.
Serving as the single filter-regulator stage at the inlet of a machine's pneumatic manifold, giving the panel one drain point, one gauge and one pressure setting for the whole circuit.
Step up or down through the GFR sizes (200, 300, 400, 600) so the port and body match the flow your line needs; this unit is the size 400 with 1/2 inch NPT threads. Choose the drain to suit access: manual (as here) for periodic hand draining, automatic or differential-pressure where the unit is hard to reach. Pick the 40 um standard element for general air preparation, or order the W variant for 5 um. Gauge scale can be MPa, psi or bar, and threads come as PT (standard), G or NPT. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR400 series as curves, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the datasheet flow figures for this unit on request before you order.
The M in the code specifies a manual drain: you open it by hand to empty collected water from the bowl. The GFR family also offers automatic drain (code A) and differential-pressure drain (blank) for installations that are not checked daily. This unit's manual drain pairs with a 0.05-0.9 MPa (7-130 psi) regulation range and the standard 40 um element.
